Large CNC machining is developed from CNC turning and milling machines.
The big difference between large CNC machining and CNC turning and milling machine is that the machining center has the ability to automatically exchange machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed by the automatic tool changer in one clamping to realize multiple machining functions.
With the development of technology, large CNC machining has continuously improved the shape and structure of mechanical products, and the requirements for the quality of parts processing have become higher and higher. This makes CNC machine tools widely used in production, and continuous development.
Especially with the rapid development of flexible manufacturing systems and the rise and maturity of computer integrated manufacturing systems, high demands are placed on CNC systems for machine tools. Modern CNC machine tools are developing in the direction of high speed, high automation, high flexibility and perfection.
1. The number of tooling is greatly reduced, and complex tooling is not required for processing parts with complex shapes;
2. The processing quality is stable, the processing accuracy is high, and the repeat accuracy is high, which is suitable for the processing requirements of aircraft;
3. The production efficiency is higher in the case of large CNC machining with multiple varieties and small batch production. Large-scale CNC machining can reduce the time for production preparation, machine tool adjustment and process inspection. Moreover, the cutting time is reduced due to the use of the optimal cutting amount;
4. It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.
